Security fixes: With the Alpha 3572.0.1, Beta 3549.1.1, Stable 3510.2.1, LTS 3033.3.12 release(s) we ship the fixes for the following CVEs

  • Linux (Stable)

    • CVE-2022-4269 CVSSv3 score: 5.5(Medium)
      A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.

    • CVE-2022-4379 CVSSv3 score: 7.5(High)
      A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel. This flaw allows an attacker to conduct a remote denial

    • CVE-2023-1076 CVSSv3 score: 5.5(Medium)
      A flaw was found in the Linux Kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While it will be often correct, as tuntap devices require CAP_NET_ADMIN, it may not always be the case, e.g., a non-root user only having that capability. This would make tun/tap sockets being incorrectly treated in filtering/routing decisions, possibly bypassing network filters.

    • CVE-2023-1077 CVSSv3 score: 7.8(High)
      In the Linux kernel, pick_next_rt_entity() may return a type confused entry, not detected by the BUG_ON condition, as the confused entry will not be NULL, but list_head.The buggy error condition would lead to a type confused entry with the list head,which would then be used as a type confused sched_rt_entity,causing memory corruption.

    • CVE-2023-1079 CVSSv3 score: 6.8(Medium)
      A flaw was found in the Linux kernel. A use-after-free may be triggered in asus_kbd_backlight_set when plugging/disconnecting in a malicious USB device, which advertises itself as an Asus device. Similarly to the previous known CVE-2023-25012, but in asus devices, the work_struct may be scheduled by the LED controller while the device is disconnecting, triggering a use-after-free on the struct asus_kbd_leds *led structure. A malicious USB device may exploit the issue to cause memory corruption with controlled data.

    • CVE-2023-1118 CVSSv3 score: 7.8(High)
      A flaw use after free in the Linux kernel integrated infrared receiver/transceiver driver was found in the way user detaching rc device. A local user could use this flaw to crash the system or potentially escalate their privileges on the system.

    • CVE-2023-1611 CVSSv3 score: 6.3(Medium)
      A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This flaw allows an attacker to crash the system and possibly cause a kernel information lea

    • CVE-2023-1670 CVSSv3 score: 7.8(High)
      A flaw use after free in the Linux kernel Xircom 16-bit PCMCIA (PC-card) Ethernet driver was found.A local user could use this flaw to crash the system or potentially escalate their privileges on the system.

    • CVE-2023-1829 CVSSv3 score: n/a
      A use-after-free vulnerability in the Linux Kernel traffic control index filter (tcindex) can be exploited to achieve local privilege escalation. The tcindex_delete function which does not properly deactivate filters in case of a perfect hashes while deleting the underlying structure which can later lead to double freeing the structure. A local attacker user can use this vulnerability to elevate its privileges to root.
      We recommend upgrading past commit 8c710f75256bb3cf05ac7b1672c82b92c43f3d28.

    • CVE-2023-1855 CVSSv3 score: 6.3(Medium)
      A use-after-free flaw was found in xgene_hwmon_remove in drivers/hwmon/xgene-hwmon.c in the Hardware Monitoring Linux Kernel Driver (xgene-hwmon). This flaw could allow a local attacker to crash the system due to a race problem. This vulnerability could even lead to a kernel information leak problem.

    • CVE-2023-1989 CVSSv3 score: 7(High)
      A use-after-free flaw was found in btsdio_remove in drivers\bluetooth\btsdio.c in the Linux Kernel. In this flaw, a call to btsdio_remove with an unfinished job, may cause a race problem leading to a UAF on hdev devices.

    • CVE-2023-1990 CVSSv3 score: 4.7(Medium)
      A use-after-free flaw was found in ndlc_remove in drivers/nfc/st-nci/ndlc.c in the Linux Kernel. This flaw could allow an attacker to crash the system due to a race problem.

    • CVE-2023-23004 CVSSv3 score: 5.5(Medium)
      In the Linux kernel before 5.19, drivers/gpu/drm/arm/malidp_planes.c misinterprets the get_sg_table return value (expects it to be NULL in the error case, whereas it is actually an error pointer).

    • CVE-2023-25012 CVSSv3 score: 4.6(Medium)
      The Linux kernel through 6.1.9 has a Use-After-Free in bigben_remove in drivers/hid/hid-bigbenff.c via a crafted USB device because the LED controllers remain registered for too long.

    • CVE-2023-28466 CVSSv3 score: 7(High)
      do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference).

    • CVE-2023-30456 CVSSv3 score: 7.8(High)
      An issue was discovered in arch/x86/kvm/vmx/nested.c in the Linux kernel before 6.2.8. nVMX on x86_64 lacks consistency checks for CR0 and CR4.

    • CVE-2023-30772 CVSSv3 score: n/a
      The Linux kernel before 6.2.9 has a race condition and resultant use-after-free in drivers/power/supply/da9150-charger.c if a physically proximate attacker unplugs a device.
